| 摘要 |
The electropyrotechnic igniter (1) comprises a body divided into a downstream chamber and an upstream chamber by a discoid metal piece (8), the downstream chamber containing a resistive heating element (11), a pyrotechnic initiating composition (12) and a pyrotechnic ignition composition (7), and the upstream chamber containing a rectangular electronic card (17) extended by three external metal pins (29 to 31), on which electronic card conducting tracks are provided. Two metal connection pins (13, 14) pass through the discoid metal piece (8) and connect the said conducting tracks to the resistive heating element (11). A means of intercommunicating and of triggering a train of specific electric pulses as well as a means of storing electrical energy are connected to the conducting tracks. This igniter is more especially intended to be used in motor-vehicle safety, especially for constituting the device for igniting a gas generator associated with an airbag.
